The winter issue of Robot magazine contains a comparison of the various programming solutions for the NXT. It’s available online at http://www.botmag.com/articles/10-31-07_NXT.shtml. The comparison includes implementation of a simple line following program using the different programming languages including screenshots from the different environments. [Note: I wrote the article and also helped author ROBOTC].

Another NXT programming language discussion was justed posted on the Wired magazine web site at http://blog.wired.com/geekdad/2007/11/the-best-progra.html. Chris Anderson of Wired has been using his NXT to control his UAV — Unmanned Aerial Vehicle — and has tried many of the programming environments.
